while playing with the NEWT FE to see what the GTK FE still misses i
noticed some things that can be improved

-"error", "text", "note" questions in the GTK FE are displayed by the
same question handler, while the NEWT FE flashes in red the screen when
an error question is diplayed.
Shouldn't also the GTK FE act somehow this way, maybe displaying a "i"
icon aside the question when displaying a "note" or a "text" question,
an "!" icon when displaying an error?
Eduard, can you draw those icons? if i'm not wrong some times ago you
drew an "i" (red) inside a circle (red) icon in some of your screenshots

-When pressing "ESC" you get back to the main menu: should the GTK
frontend implement such a functionality?

-It would be nice if you could automatically activate "Back" button by
pressing "BackDel" key (the key above "Enter" on the keyboard)

-A text is displayed in the bottom part of the screen and tells the user
about shortcut shortcut commands: shall the GTK FE display this string
too? maybe in a statusbar at the bottom of the screen?

-As "execute a shell", neither "configure base sytem" works in the GTK FE
what do you think ?
ciao
